Thanks for clearing up the size of the test pipe !

Lsdunique, I would like to purchase a set of these test pipes....please send me an email when you get a chance. Thanks.

 

MaxHax :

just wanted to let you know that stillen has a really nice set of long headers you might want to look into. replaces cats! would go really nice with the ati. but be aware that your 7psi pulley will only give you about 5. but your rwhp will be alot more then the 363 you have now.

 

L/T's are not smog legal here but I have Borla's and they work fine. I want to stay streetable and Borla is doing the job.

Thanks though!

 

could you make them in 3" piping and how much?

 

i would be happy if you can make them 2.5"

 

Happen to have a pic of this? My engine bay is the race type look and this part sounds cool.

What piping is my Borla true dual? Someone said 2.25 but isn't it 2.5?

 

lsdunique
you have a pm from me on the off raod pipes. i am a serious buyer please respond. thanks CJ

 

Not to speak for anyone but...

lsdunique will probably not be on the boards for a few weeks. He's involved in a large project at the moment. When he returns, I'm sure there will be some good news.

 

OK, then how do we order? The email addresses on the site do not work.

 

he'll be back in sept, he is working on a show car.

PM him.

 

Mr Wazowski, do you know the details behind the show car....

Sounds like a nice project if hes tied till september!

 

Hmm..is he still fulfilling orders?

 

What is he wearing ? (oops wrong room) sorry!

 

I've been trying to reach him on a couple of e-mail addresses. No-reply.

Show Car is fine by me -- only problem is pre-paid $233. pipes never arrived???

Probably a good explanation -- but way overdue they are!!

 

very tempting stuff, but whats this about the Z having more o2 sensors?

how many are there 4? 3?


now if those cat pipes do away with 2 of the cats, what about the others?
maybe the CEL isnt going on because the 2 cats being replaced arent a big enough deal to trip the CEL
we're still getting air restriction with the left over cats.....right?

 

The Z has four O2 sensors. The first one on each side closest to the engine is used to provide feedback regarding A/F ratio. The second O2 sensor on each side is strictly used to monitor emissions (i.e. to verify that you have cats installed). The downstream O2s are not used by the ECU for any tuning purposes.

The stock pipes that are being replaced with these straight pipes contains BOTH the precat and main cat. So, by using these pipes, you will be eliminating all four cats from your car. This being said, I don't understand myself why the CEL is not going off... I'm just glad it's not. Ignorance is bliss!
